Solution Review: Print All the Paths
Understand how to implement a depth-first traversal to print every path from the root to leaf nodes in a tree. This lesson guides you through using a stack to track nodes, printing paths at leaves, and managing recursion with efficient time and space complexity.

Solution
For this problem, we’ll use a stack and follow the depth-first approach. Whenever we traverse a node, we’ll add that node to the stack. When we reach a leaf, we’ll print the whole list (from the root node to that leaf node). When we return from the function, we’ll remove the element that was added to the stack ...
